SenseCAP M2, the Helium data-only hotspot, (close to be) ready-to-go

Sensecap M2 – data only

Until now, all the Helium data-only hotspot I have been tested where DiY devices. They are not really complicated to manage but they are not ready-to-go, so you need to manually on-role them with a wallet and some complex CLI operation for the non-experts. This SenseCAP M2 is the first one I’m testing, ready-to-go or close to be ready-to-go (that does not means it is the only one existing).

As it is a Data-Only hotspot, it means it does not participate to the Proof of Coverage, as a consequence, there is no related rewards for this device. This device only earn the DC (Data Credit) for transferring the communications, so $1 for 100.000 packets. Before getting question, this have no return on invest in a crypto point of view. This has been made to help supporting professional applications on the Helium network.

Astrocast, another route to the space IoT

In some of my previous post, I did talk on Kineis IoT satellite solution. The competition is that area is large and one of the other player is Astrocast. I really thanks them for getting me in the program to explore this technology (and I apology to have been a bit long to start using it).

Astrocast is a Swiss company launching nanosatellites to currently provide Europe, Asia, Africa coverage for IoT. It uses L-Band (1-2 GHz) radio. The transmission period will be 15 minutes once the constellation will be fully deployed. The current constellation is 10 satellites for a target of 100 satellites by 2025.

What positions for 5G and other wireless technologies in the industrial world?

The industry is changing, digitalizing, let’s call it the industry of the future or industry 4.0, it is increasingly integrating data into decision-making. If data has been driving the industry for a long time, we are now talking about another scale, that of massive data, on which it is possible to make faster, more efficient, more relevant decisions with impactful effects.

The quality and performance of the decision is directly related to the diversity and quantity of data processed for decision making. The industry already produces large volumes of data from production processes which already allow a strong creation of value using industry 4.0 solutions. The capture of industrial data then develops in its diversity component to pass a new stage, bringing a look upstream and ahead of the production chain.

This data collection is made possible through new communication technologies such as 5G, but not only. After having experienced the media campaigns on the impact of 5G in the industry, and elsewhere, at the beginning of 2021, I will try to present where to position this technology by its singularities.

Is Sigfox finished?

Since yesterday, the microcosm of the IoT has been in turmoil, Sigfox, the Toulouse company, pioneer of the Internet of Objects, the one which had carried out remarkable fundraising for France: 100M then 150M is placed in receivership. But is it really a surprise? Is this the end of this technology?

COTX-X3 helium miner review

After reviewing different Helium miner like RAK, Sensecap, Kerlink, Nebra… now comes the Cotx-X3 miner. This miner has a long story and a bad reputation, due to something not really clean the maker did with the first units.

This is not related to the hardware quality and I’ve been happy to buy some of them for reviewing it. This miner is a full miner, based on a standard design using a Raspberry Pi 4. It has the particularity of having a front screen and an audio jack ! Don’t laughs, the reason is simple, this device has a different usage before becoming an helium miner.

Deploying Helium-ETL instance with API

Helium blockchain ETL is basically a copy of the Helium Blockchain into a database. That way you can query the helium blockchain history to build apps like monitoring, tax management…

The Helium blockchain API project is connected to the Helium ETL to get an easy access to these data.

I’m currently building a tool to monitor and alarm a fleet of hotspots (stay tuned) and it currently uses the Helium API (api.helium.io). But helium APIs are a bit overloaded and not made to support high rate querying from each of the application any member of the community is developing. So I’ve been decided to make my own instance of ETL and API for my own purpose. This is the experience I’ll describe in this blog post:

Helium solar hotspot (Data-Only) 2021 update

In a previous blog post about 18 month ago, I designed my first Low Cost LoRaWAN Solar Gateway. This year, I did some updates to create a new version to support Helium Data-Only Hotspot (basically it works for any LoRaWAN networks like TheThingsNetwork).

In this version, I’m using a RAK wisegate Lite gateway, it is a bit more power consuming than the TTIG but can work on any LoRaWAN network. I’ve also changed the outdoor enclosure to get a larger and single battery.

You will also see that I’ve been updated the monitoring dashboard to get something better and free of charge. Two of them are in production. One is already deployed as an upgrade of the 1st one and the second one is in the testing phase. The First version has been on the field for more than a year. It has been offline about 10 days during that year, due to the weather conditions. This is a service level of 98,29% from its start until now. With the larger battery I’m expecting to resolve some of the small service interruption I’ve issued during last winter.

Helium Kerlink Miner iFemToCell

Kerlink Helium Miner iFemToCell

Kerlink is a LoRaWan hardware player since the first ages of this technology. This French company has equipped most of the operator’s network and is used to propose high quality industrial products.

The iFemToCell is not a new product. It exists since a couple of years and I already tested the IFemToCell 4 years ago. Recently the company has created a Helium edition we are going to review in this blog post.

This is an interesting device as it is a kind of hybrid between a light miner and a full miner. Even if the Kerlink platform is powerful, it is far away the power of a raspberry Pi and certain operations like consensus group can’t be performed. As this is now delegated to Validator, this difference have no impact on rewards. In another hand, this device is consuming less power and it is possible to power it with sun more easily. This is quite interesting.

Let see what is this device and what is specific during its deployment.
